Abstract: To prevent overheating caused by insufficient cooling of an exhaust valve and solve problems caused due to a structure, in which combustion gas and supply air flow from a lower part to an upper part of an engine thus making an uncombusted fuel, the combustion gas, and residues of the combustion gas more likely to remain in a cylinder, in a form in which the exhaust valve is installed at an engine top part.SOLUTION: An exhaust valve form is reformed to provide an air supply valve 9, an exhaust hole 8a, and a mechanism which opens or closes the exhaust hole 8a and cause supply air and combustion gas to flow from an upper part to a lower part of a cylinder 1b. The supply air (air) cools the air supply valve 9 itself and removes the combustion gas from an area near a combustion chamber quickly. Concurrently, the combustion gas and residues of the combustion gas are discharged to the outside of the cylinder to avoid occurrence of preignition and knocking caused by spontaneous firing of the combustion gas and the residues during premix combustion. Furthermore, a structure of an engine is provided that avoids use of a high-grade alloy for dealing with increase of a temperature of a conventional exhaust valve and solves problems of maintenance caused by the exhaust valve being heated to high temperature.SELECTED DRAWING: Figure 1
